.BEAMING MACHINE.

Application filed November 6, 1928. Serial No 317,645.

In machines for beaming warps the rotary driven means with which thebeam is coupled has a member thereof toothed and with the teeth of suchmember a holding pawl engages which, when the operator stops the drivingaction, as by shifting a belt or other movable means to apply the powerto or cut off the power from said driven means, serves to preventbackward rotation of the beam and consequent slackening of the warpbetween the beam and the (usually braked) reel from which the warp isunwound. According to this invention the pawl is connected with the saidmovable means in such manner that when the said means is moved to applythe power the pawl will be retracted, thus to avoid the monotonous andhence objectionable clicking sound of the pawl as it rides the teeth ofsaid member, the pawl being allowed to assume its normal or workingrelation to said toothed member when said means thereupon is moved tothe position for cutting oil' the power. Usually the driven meanscomprises two parts as to which one, due to a spline connection, isshiftable for certain purposes, together with the pawl, lengthwise ofthe axis of the beam and the said movable means includes an actuator inthe form of a treadle extending parallel with the axis t the beam. Theinvention, where these conditions exist, contemplates obtaining theretraction of the pawl from this actuator, and takes into account theshiftability of said part and pawl relatively to the actuator.

1 is the frame including a pair of horizontal bars 1 and a third bar 1and a bracket 2 fixed on these bars. 3 is the beam journaled at itsleft-hand end in one of two brackets 4, I

4* (which are shiftable along bars 1 to or from each other or togetherand are connected eludes the intermeshing gear 6 and pinion 7 (theformer of which is the part carrying the right-hand end of the beam, towhich it is lashed by the means 8), the shaft 9 journaled in bracket 2,and the fast pulley 10 on said shaft, the shaft being held againstlongitudinal shifting in bracket 2 whereas the gear and pinion areshiftable lengthwise of said shaft and with bracket 4: (to wit, if thecarriage as a whole is thus shifted or said bracket is thus shifted toor from bracket 4); the connection between the shaft and the pinion(carried thereby) is a spline 9. The means to apply or cut off thepower, which is here derived from a going pulley 11, is a belt 12 whichmay run idly on a free pulley 13 on shaft 9 and is shiftable onto pulley10, a shiftor 14 for the belt, a treadle lever (actuator) 15 having itsaxis and its treadle 15 parallel with the beam and a flexible connection16 which extends from theshifter to the treadle lever and shift-er) tohold said means in theposition where the belt is on the free pulley. 20is the holding pawl normally (by gravity) held engaged with the teeth ofgear 6, being pivoted on bracket 4. 21 is the reel and 22 its brakingmeans. So much is known.

The means to apply or cut off the power is made, according tonay-invention as stated, to actuate the pawl to retract it from the gearwhen the treadle lever is depressed to effect the coupling and start thebeam rotating to wind thereon the warp. Thus, a shoe by its weight restson the treadle and inasmuch as it moves up and down therewith it is, toall intents and purposes, a part of the said means; this shoe comprisesan arm 23 pivoted in a depending leg 24 of the bracket 4 of the carriageand a roller 25 journ aled in the arm I on a horizontal axis transverseof the treadle. Connecting the (arm of the) shoe with an .arm 20 of thepawl is a flexible connection 26. Whenever the treadle lever isdepressed to apply the power to the driven means it will be apparentthat the means therefor, as thus organized, will elevate the pawl clearof the teeth of the gear, allowing it, however, to return to hold thegear and hence the beam against any back-lash on the ensuing rise of thetreadle lever. The construction and arrangement are moreover such thatthe means to apply and cut off the power remains operative on the pawlin this way wherever the bracket, and hence the part 6-7 of the drivenmeans and the pawl, happen to be set in their range of shiftinglengthwise of the axis of the beam. 5

Describing certaiirparts of tl'ie'meclianism shown more particularly:Leg 24 is bolted to bracket P and projects above its table 4 which hasits right-hand edge portion up turned as shown in Figs. 3 andd and insuch portion has an opening H. An elongated. piece 27, grooved at theunder side and forked at both ends", rests onthe table and pentrat'essaid opening and has in its forks the grooved sheaves 28 and 29. onefork depending and being engaged with the'left-hand edge of the tableandthe other bearing upwardly against the bracket. Theeonneetion 26extends over sheave 28 and then under sheave 29 to the pawl. The piece27and its sheaves simply form an adapter for the bracket 4 whereby it willserve forthe anti-friction guiding of the connection 26.

In the preferred construction (as shown) the member 2325 is carried byand thus confined to shift with the carriage section or bracket 4, towit, 'beingmounted in its depcnding' leg 2-1. lVith the member 28'25"thus confined to shift with thesaid carriage secti'onthe shiftingof saidmember alting the treadle lever is an automatic incident oftheshiftingof said section, in consonance there with.
